「辽源伸缩门」不锈钢伸缩门开焊的原因和处理

电动伸缩门有不锈钢和铝合金两种材质，在款式上，每个厂家有很大的区别，使用于不同的场所，有不同的风格，这样更能彰显企业的文化形象。


Electric telescopic doors are made of stainless steel and aluminium alloy. Each manufacturer has a great difference in style. They are used in different places and have different styles, which can better show the cultural image of the enterprise.



辨别一条电动伸缩门质量的好坏，不仅要从款式，材料，做工是否精致也是重要因素之一，一个注重产品质量的厂家，肯定会在生产的过程中，对于产品的细节保持极高的制作和检验要求。


Discerning the quality of an electric telescopic door not only depends on the style, material and workmanship, but also is one of the important factors. A manufacturer who pays attention to the quality of products will definitely maintain a very high production and inspection requirements for the details of products in the process of production.


有些伸缩门使用过一段时间之后，会出现焊缝开裂的情况，也就是开焊，这就是与制作师傅的技术有关的，说明其不够专业。


After some expansion doors have been used for a period of time, there will be weld cracking, that is, open welding, which is related to the technology of the manufacturer, indicating that it is not professional enough.

Reasons for Opening Welding of "Liaoyuan Telescopic Door" Stainless Steel Telescopic Door and Treatment Method


造成焊缝开裂的原因，宏创伸缩门厂家的看法比较统一，其主要原因是焊接工艺存在问题，焊角强度达不到应有的数值，导致焊角开裂。


Hongchuang expansion door manufacturer has a unified view on the causes of weld cracking. The main reason is that there are problems in welding process, and the strength of weld angle can not reach the proper value, which leads to the cracking of weld angle.




以下几方面的焊接工艺将对焊角强度产生直接的影响，也对焊缝开裂产生重要的影响，值得注意：


The following welding processes will have a direct impact on the angular strength of the weld, and also have an important impact on the cracking of the weld. It is worth noting that:


1、型材下料的几何尺寸精度，，如长度、角度，框和扇的对角线公差，厂家建议必须保证在2 n～3咖以内，以避免焊接余量和焊接熔化量不均，焊角强度降低，同时可避免在焊角产生过大的内应力。


1. Geometric dimension accuracy of profile blanking, such as length, angle, diagonal tolerance of frame and fan, should be guaranteed within 2n~3Ca, in order to avoid uneven welding allowance and welding melting quantity, decrease welding angle strength and avoid excessive internal stress in welding angle.


2、焊板质量和焊接温度的设置。龙盛伸缩门得焊板上的温度分布必须均匀，焊板的设置温度和实际温度的吻合性要好;设置的加热温度过高或过低都将使焊角强度降低。


2. The setting of welding plate quality and welding temperature. The temperature distribution on the welded plate of Longsheng telescopic door must be uniform, and the setting temperature and the actual temperature of the welded plate are in good agreement. If the heating temperature is too high or too low, the fillet strength will be reduced.


3、进给压力的设置。焊角强度与进给压力的关系应该是：随着进给压力的增大，焊角强度增大，进给压力超过一个非常佳值时，焊角强度反而下降。


3. The setting of feed pressure. The relationship between fillet strength and feed pressure should be as follows: with the increase of feed pressure, the fillet strength increases, and when the feed pressure exceeds a very good value, the fillet strength decreases.


另外，「辽源伸缩门」宏创门业提醒要注意前后压钳压力的设置应保证型材不变形、不位移，在焊接过程中一旦型材发生位移，焊角强度将严重下降。


In addition, "Liaoyuan telescopic door" Hongchuang door industry reminds us to pay attention to the setting of pressure clamp before and after the profile should not be deformed and displaced, once the profile displacement occurs in the welding process, the angular strength will be seriously reduced.


4、型材靠板的调整和使用。必须调整好靠板的直线度和垂直度，以及靠板内侧与钳口边缘的相对位置，型材靠板调整不当，将使型材产生错位和偏熔偏焊，严重影响着型材的焊角强度。


4. Adjustment and use of profile relief board. It is necessary to adjust the straightness and verticality of the relief plate as well as the relative position between the inner side of the relief plate and the edge of the clamp. The improper adjustment of the relief plate will result in dislocation and deviation welding of the profile, which seriously affects the fillet strength of the profile.


型材靠板高度应与型材高度相协调(前者稍低)，有些组装厂靠板不周全，用小系列型材的靠板来焊大宽度的型材，这是不可取的。


It is not advisable for some assembly plants to weld large-width profiles with small series profiles because the height of profiles should be in harmony with the height of profiles (the former is slightly lower).


5、焊布的质量和洁净。对于使用期限已过或已穿孔的焊布应及时更换，同时应注意维持焊布的洁净，有粘附物要及时清除。


5. Quality and cleanliness of welding cloth. Welding cloth that has passed the service life or perforated should be replaced in time. At the same time, attention should be paid to maintaining the cleanliness of the welding cloth, and the adhesives should be removed in time.


有些组装厂为了节省工时，上好胶条后再焊接型材，致使焊布粘胶，弄得焊布黑黑的一片胶料，这是一种只追求效率而不追求质量的做法。


In order to save man-hour, some assembly factories put on good rubber strip and then weld profiles, resulting in the welding cloth glue, resulting in a black sheet of adhesive, which is a way of pursuing efficiency rather than quality.


「辽源伸缩门」宏创门业建议不宜接纳同一工艺参数焊接不同品种规格的型材或不同厂家的型材。


"Liaoyuan Telescopic Door" Hongchuang Door Industry recommends that it is not appropriate to accept the same process parameters to weld profiles of different varieties and specifications or profiles of different manufacturers.
